any good idea on this?

txt file like this,

1 2 3 4456
a bb c d 3 f e
1 k 32 d m f e
123 m 2 k


every line contains 3 or more columns, all the columns are separated by space, and every column includes 1 to 3 character.

what I wanna do is deleting the first three columns, and keep the rest no matter how long the rest will be, is there a fast way to do this?

NAME
neaten - neaten up output columns SYNOPSIS
neaten [ format ] DESCRIPTION
Neaten reads from its standard input and neatens up columns separated by white space using the specified format. The format is a string consisting of a positive integer followed by an alignment character and another integer. The alignment character is usually a decimal point ('.'), but it can be any non-digit. The alignment character is used as the central point of each column. The total column field width will be the number to the left of the alignment character plus one for the alignment character itself plus the number to the right of the alignment character. If a field does not contain the alignment character, it will be printed to the left of where the alignment character would have appeared. If a field is too long to print within the specified format, the entire field will be printed and that row will not be aligned with the rest. The default format is "8.8". EXAMPLE
To examine a file with columns of numbers: neaten 10.8 < input | more BUGS
Columns wider than the total width of the format specification will be printed without any separating white space. The program does not do anything special with tabs on the input. AUTHOR
